Which hepatitis causes more morbidity in pregnant female?
**Core Concept**
Hepatitis in pregnancy poses significant risks due to the immunological and physiological changes associated with pregnancy. The severity of hepatitis can be exacerbated by the increased metabolic demand and the potential for exacerbating underlying liver dysfunction.
**Why the Correct Answer is Right**
Hepatitis B is the primary cause of morbidity in pregnant females, particularly due to the risk of vertical transmission to the newborn. This occurs through the transplacental transmission of hepatitis B surface antigen (HBsAg) from the mother to the fetus, leading to severe neonatal hepatitis and a high risk of developing chronic hepatitis B infection. The risk of transmission is significantly reduced with the administration of hepatitis B immune globulin (HBIG) and the first dose of hepatitis B vaccine within 12 hours of birth.
**Why Each Wrong Option is Incorrect**
**Option A:** Hepatitis A is primarily spread through the fecal-oral route and does not pose a significant risk of vertical transmission during pregnancy.
**Option B:** Hepatitis C is also transmitted vertically, but the risk is lower compared to hepatitis B, and the clinical manifestations are less severe.
**Option C:** Hepatitis E is a major cause of fulminant hepatic failure in pregnant women, particularly in regions with poor sanitation. However, it is not the primary cause of morbidity in pregnant females.
**Clinical Pearl / High-Yield Fact**
Hepatitis B vaccination is recommended for all pregnant women, particularly those with a history of hepatitis B infection or exposure risk. Administering the first dose of hepatitis B vaccine within 12 hours of birth significantly reduces the risk of vertical transmission.
**Correct Answer:** C. Hepatitis E causes more morbidity in pregnant female.
